I. Application tiled October 22j 1917i VSeriyal No. 197,858.

Referring to i lie. d i'a ii" iii'gia. 1.,i utllcate the' i 'fliixi'hle sheet to whiwli the :irinoi plates are apl'iliedniiid sheet living! preferably of canvas although not necessarily limited tothat pai'tii'ulai' umtoiiiil. l

2 indicates the armor plate-i wliehaie f lines in Fig. .1`v witl'i their sideurespectively-- parallel with and .ianin'eise tothe circumferential lines of tlie tii'e; It is Ordinarily more convenient to apply the plates to the fabrilwitl-i Aeinall spaces iiiteii'oning between one plate and the next. as indicated :it- 3 in Fig. 1 and I lei-iii the lines along which thel plates have their edgtw slightly spaced apart, the joint line nl' said i'oii's of plates.

-l indu-atei: tlitl platine: ou the opposite. and .pietei'alily exterior ifool' theA dieet. These plates; -l mai' he ot iilieiaiitially the saline .aliape as the pla tei-` L. and they :ii'e :iiianged iii longitudinal and transverse rowshut. the' arrangement H'sui-li that the lines of the is o' sides of the plates :ii-e diagonal'to the Ci1-` euiiifei'eiitial linenV ol' the iii-e and to thesldes of the pliites 2. .l also prefer to arrange *lie plates l close enough together so that lieii" exti'eniltie# oik t'oiuei-sV will lap one upon another. as Aalioii'u iii Figs. 1 and Q, tlieieliy entirely o\'ei'iii,i r ei'el'li possible joint. oi' intei'slim` willi a protectingshield of metal.

The platte-2 and l are oriliiiaiily of tl1in i'oeilient steel. although other suitable metal ma)r he employed. V

The plates lai-e fi'iiili" cemented and :it-- taolietl to the .sheet l. and the underneath layer of the plateel Al may he moije oi' less {.iiesisml into aud ouilioddel in the fabric. In.

` 1` Fig; l the i'ulilieror other vement by which ou line llllll llie plate l aruiiitavlied is iiulitatetl at 5i 'Changes uml iai'ialiouh may be made iii the details of the device without departing from the spirit of the invention, and such changesand variatiol'isl are contemplated fall within the scope of the claimsl appended hereto.

lVhat is elafilned is:

1. In an-arniored tire, in combination, an inner tube, :in exterior carcass, and a protecting layer consisting of a- Hexible sheet having substantially rectaligular metal plates attached to opposite sides of the same, the plates on one side of said sheet being arranged in rows with their edges respectively )arallel withl and transverse to the eireum ei'ential lines of the tire, and the plates on the other side of said sheet being arranged opposite the joint lines of the first mentioned plates and with their sides diag' onal to said rireulnferential lines and with their corners lapped.

A puncture-res1stmg device adapted to be combined in an armored tire, consisting oi a liexible sheet having substantially reetangnlar metal plates attached to opposite of the same, the plates on one side of said sheet being arranged in rows With their edges respectively parallel with and transverse to the circumferential lines of the tire, and the plateson the other side of said sheet being arranged opposite the joint lines of 1nd widely spaced apart at their sides and with their extremities only lapped.

In testimony whereof I aiix my signature hereto.
